PULL SWITCH.

Application filed May 18, 1922. Serial No. 561,862.

To all 1o/10m t may concern.'

Be it known that I, REUBEN B. BENJAMIN;

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Pull Switch, of which the following is a full, clear, concise, and

exact description7 reference being had to the accompanying drawing; forming a part of this specification.

My invention relates to pull switches.

One of the objects of my invent-ion is to provide means for facilitating the installation of a pull switch mechanism in a canopy'.

A further object of my invention is to provide an adjustable chain guide for the pull chain of a pull switch to enable the chain to be led in any desired direction, thereby facilitating its installation in a canopy.

Further object-s will appear from the detailed description to follow andl from the appended claims.

In the drawings in which my invention is illustrated- Figure 1 is a vertical sectional view showing a pull switch mechanism installed in a ceiling canopy;

Fig. 2 is a vertical axial section showing a pull switch mechanism installed in a side wall canopy;

Fig. 3 is a side view of the switch bracket and switch;

Fig. 4' is a section on the line 4 4 of Fig. 3;

Fig. 5 is atop plan view of the switch bracket and switch;

Fig. 6 is a side view of the switch mechanism;

Fig. 7 is a side view of the other side of the switch mechanism; 'and Fig. 8 is a section on the line 8--8 of Fig. 7

Referring now to the drawings in detail and rstto the ceiling construction shown -in Fig. 1, this comprises a pull switch 10, mounted on a switch bracket 11 in the canopy 12. One end of the switch bracket 11 is secured onto the fixture stud 13, a fixture stem 14 being screwed into the other end of the switch frame. v

The canopy 12 is provided with an opening at 15 through which extends the elongated chain guide 167 which conducts the pull chain 17 from the switch mechanism to the opening in the canopy.

In order to facilitate the installation of the switch mechanism in the canopy this chain guide 16 is made angular-ly adjustable with respect to the switch mechanism so that it can be adjusted so as tov pass through the opening 15 in the canopy. rlhe chain guide 16 has a range of adjustment from the full line position to the dotted line position shown in Fig. 1. Tith this range of adjustment it will be seen that the chain guide can be adjusted to accomodate itself to different canopies in which the hole for the passage of the chain may be differently arranged.

As shown in Figs. 1 and 8 this angular adjustment of the chain guide 16 is effected by mounting it on a curved bracket 18 mounted on the insulating base `19 of the switch. The curved bracket 18 is provided with a slot 2O in which the chain guide 16 is adjustably mounted, the threaded shank 21 (Fig. 8) of the` chain guide extending through this slot and being threaded into a nut 22. By screwing the threaded shank 21 tightly into the nut 22, the chain guide 16 is firmly clamped in adjusted position on the curved bracket 18. In order to prevent the nut 22 from turning when the shank 21 is screwed into it, the bracket 18 is provided with a pair of flanges or side wings 23 which embrace the nut and prevent it from turning.` In order to keep the nut 22 from dropping out when the shank is completely unscrewed from the nut, the bracket is provided with a turned up end 24.

The bracketI 18 is held in place on the insulating base 19 by means of a pair of screws' 25Y which also serve to hold the switch on the switch bracket, this construction being shown in Fig. 4, which shows the screws 25 extending through registering openings in the switch bracket 11, the curved bracket 18 and the insulating base 19. and threaded into anchorage brackets 26. These ranchorage stampings 26 also serve as' an anchorage for the screws 27 which hold the insulating cover 28 for the switch mechanism in place on the insulating base 19.

The switch mechanism shown'may be of any suitable type. As shown it comprises a rotatable commutator 29 which controls the circuit between the two wiring terminals 30 and 31.

rlhe construction shown in F ig. 2 is substantially the same as that just described, except that here the switch bracket 1l is screwed onto a fixture stud 13 seated in an outlet box 32. A canopy or cover 33 is provided for the outlet box, having an opening 34 through which the chain guide 16 extends. The chain guide is adjustable from the full line to the dotted line position shown in the ligure, so that it can readily be adjusted to accommodate itself to differences in location of the opening 34C in the canopy.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States isl. The combination with a canopy having an opening therein, of a pull switch comprising an insulating base mounted in fixed position with respect to said canopy, a pull switch mechanism mounted on said insulating base, a pull member, and a guide for said pull member adjustable with respect to said insulating base, whereby it may be adjusted to bring the pull member out through said opening.

2. The combination with a canopy having an opening therein, of a pull switch comprising an insulating base mounted in fixed position with respect to said canopy, a pull switch mechanism mounted on said insulating base, a pull member, and an elongated guide member for said pull member angularly adjustable with respect to said insulating base, whereby it may be adjusted to bring said pull member out through said opening.

3. A pull switch device comprising a fixed insulating base, a pull switch mechanism mounted thereon, a pull member, and an elongated guide member for said pull member angularly adjustable with respect to said insulating base, whereby it may be adjusted to lead the pull member in a desired direction.

In witness whereof, I have hereunto subscribed my name.
